Tsurayya Nurrahma

Tsurayya is a Senior Associate in the firm’s renowned Competition & Antitrust Practice Group, bringing a rare and powerful combination of economic and legal expertise to the forefront of her advisory work. Since joining Assegaf Hamzah & Partners in 2013 as an economist, she has played an integral role in some of Indonesia’s most complex and high-stakes competition law matters.

Tsurayya holds a bachelor’s degree in economics from the University of Indonesia and a graduate degree in economics from the University of Amsterdam, with a specialization in industrial organization, market regulation, and competition and antitrust policy. In 2024, she further strengthened her multidisciplinary approach by earning a bachelor’s degree in law, equipping her to navigate both the economic and legal dimensions of regulatory challenges.

With over a decade of experience, Tsurayya has been deeply involved in numerous significant cartel investigations, abuse of dominance cases, and merger control notifications across sectors such as energy, infrastructure, fast-moving consumer goods, manufacturing, telecommunications, and digital markets. Her insights have proven essential in designing competition strategies, preparing economic submissions to the Indonesian Competition Commission (KPPU), and defending clients in contentious proceedings.

Her experience extends to advising on competition compliance frameworks, assessing risk exposure in cross-border transactions, and assisting multinational clients in aligning their operations with Indonesian competition laws. She routinely collaborates with legal teams to deliver robust, data-driven arguments supported by market analysis, financial modeling, and cost structure evaluations.

Tsurayya’s strength lies in applying advanced economic methodologies to legal contexts. Her capabilities include:

• Market definition and competitive assessment
• Dominance analysis and pricing strategy evaluation
• Quantitative modeling of anti-competitive effects
• Economic due diligence for merger control
• Cost-benefit and impact assessments in regulatory matters

In addition to her antitrust work, Tsurayya has developed strong expertise in halal product assurance regulations, a field increasingly significant in both domestic compliance and international trade. Her understanding of the regulatory landscape, supported by in-depth legal and economic analysis, makes her a key advisor for businesses navigating halal certification and product assurance requirements in Indonesia.

Tsurayya also supports government agencies, development institutions, and private entities in regulatory and public policy projects, offering economic analysis to support legislative reforms, regulatory simplification, and the reduction of administrative burdens.
